They only sent 4 tasks to do, don't waste your time. The tasks were mostly to evaluate our approach to solving abstract problems, but safety tests isn't something that should be decided solely by a tester.

It was a four step interview process. The first step was a technical take home task for initial screening. I was asked to estimate the number of mechanical scales in the Czech Republic and to describe tests I would run on an electric scooter before it would be released for use. After the technical task I was invited to the second stage, which had two parts. The first part was an online questionnaire with the HR representative. It included questions about networking, logic puzzles, general Windows/Linux knowledge, and a section where I had to describe a comprehensive testing process for a household scale. The second part of that stage was a discussion with a team lead. Mainly focusing on the household scale testing task and turned into an engaging back and forth conversation about my approach and reasoning. After that, I was invited to a 30 minute technical preparedness interview, This focused exclusively on networking topics like DHCP, DNS, subnet masks, DNS records and other related concepts. The final step was a two hour interview with three team leads consisting of three parts. One team lead focused on logic puzzles, another on networking, and another on QA. The team leads and the HR representative were very nice throughout the entire process. I got the impression that the company is friendly and welcoming. Overall, although a four step process was naturally anxiety inducing, the interviews themselves were very enjoyable and well structured.
